Definitions

  • the present invention relates to content management in a home network.
  • the number of consumer devices for storing and rendering audiovisual content has dramatically increased in the last years and is expected to continue to do so in the future. It is not unusual to find within a typical house a home network including multiple TV sets, set top boxes, DVD players, and multimedia mobile phones. These devices consume content from a wide range of sources such as broadcast networks, internet streaming servers, personal video recorders, local music library services, local photo archives, etc.
  • the Digital Living Network Alliance is a non-profit trade organization that is a result of one such collaboration between more than 250 member companies.
  • the DLNA standard provides a protocol for using and sharing content between home networked devices.
  • interoperability standards include e.g. Universal Plug and Play (UPnP) , Home PNA (HPNA) , and custom implementations from various operators.
  • UPF Universal Plug and Play
  • HPNA Home PNA
  • custom implementations from various operators There are many products and home network servers that support DLNA and other similar standards.
  • the devices within the home network can share information, about their content and device resources, these devices are typically not capable of sharing this
  • Such sharing sometimes could also be desirable, e.g. to enable making all services that can be offered over the entire collection of content available to a particular user.
  • alliances is to add more capabilities to the devices in a home network so that these devices can provide a more consistent view for content navigation and selection and can better manage networked resources. This approach, however, is a potential source of conflicts and may require the firmware upgrades in the devices within the home network.
  • the embodiments of the present invention are adapted to operate in an environment including at least two devices in a home network, a proxy device communicatively connected to each of the at least two devices and to an external network, and a resource server communicatively connected to the proxy device via the external network.
  • a method for the resource server to enable content navigation, discovery and management within the home network includes receiving, from the proxy device, content-related information obtained by the proxy device from each of the at least two devices, where the term "content-related information" is used to describe data regarding content available to each of the devices within the home network.
  • the method further includes generating, based on at least part of the content-related information received from the proxy device, an integrated navigation interface, such as e.g. an electronic programming guide, enabling a user in the home network to navigate and/or manage content available to all of the at least two devices.

  • One advantage of the present invention is that the user- may be provided with a consistent, integrated, view of the content available via various devices within the home network irrespective of the protocol used (DLNA, UPnP, HPNA, etc.).
  • Another advantage is that the devices within the home network are able to share information about their content and device resources with devices and/or servers outside of the home
  • Yet another advantage is that only minimal firmware upgrades are necessary for devices within the home network, as the new functionality can be implemented via changes to the resource server.
  • One embodiment of the invention may be implemented as a program product for use with a computer system.
  • the program (s) of the program product define functions of the embodiments (including the methods described herein) and can be contained on a variety of non-transitory computer-readable storage media.
  • Illustrative computer-readable storage media include, but are not limited to: (i) non-writable storage media (e.g., read-only memory devices within a computer such as CD-ROM disks readable by a CD-ROM drive, ROM chips or any type of solid-state non-volatile semiconductor memory) on which information is permanently stored and (ii) writable storage media (e.g., floppy disks within a diskette drive or hard-disk drive or any type of solid- state random-access semiconductor memory or flash memory) on which alterable information is stored.
  • non-writable storage media e.g., read-only memory devices within a computer such as CD-ROM disks readable by a CD-ROM drive, ROM chips or any type of solid-state non-volatile semiconductor memory
  • writable storage media e.g., floppy disks within a diskette drive or hard-disk drive or any type of solid- state random-access semiconductor memory or flash memory

Abstract

La présente invention porte sur la migration d'au moins une partie des tâches de découverte de contenus et/ou de gestion de ressources d'un réseau domestique vers un serveur distant au moyen d'un dispositif mandataire, tel que par exemple un serveur mandataire compatible DLNA ou un serveur mandataire compatible avec une autre et/ou une pluralité de normes, relié aux dispositifs dans le réseau domestique et relié également au serveur de ressources par l'intermédiaire d'un réseau externe. Le dispositif mandataire peut obtenir des informations relatives aux contenus, éventuellement également : des informations relatives au dispositif à partir des dispositifs dans le réseau domestique et fournir ces informations au serveur distant qui peut utiliser ces informations pour créer une interface de navigation intégrée destinée à naviguer dans et/ou à gérer des contenus disponibles pour tous les dispositifs dans le réseau domestique.
